R710 Negotiating at 100Mbps full

Running Unleased 200.13.6.1.319 and recently noticed that my R710 is only communicating at 100Mbps.  The output from my HP 2530-24G-PoEP switch shows the following:

# sh int brief

 Status and Counters - Port Status

                   | Intrusion                           MDI  Flow
  Port  Type       | Alert     Enabled Status Mode       Mode Ctrl
  ----- ---------- + --------- ------- ------ ---------- ---- ----
  1     100/1000T  | No        Yes     Up     1000FDx    MDI  off
  2     100/1000T  | No        Yes     Up     100FDx     MDIX off
  3     100/1000T  | No        Yes     Up     1000FDx    MDIX off

Port 2 is the R710 and port 3 is an R610; both ports are configured similarly on the switch. We can also see lots of errors on this port:

# sh int

 Status and Counters - Port Counters

                                                                     Flow
  Port       Total Bytes    Total Frames   Errors Rx    Drops Tx     Ctrl

  2          1,303,791,737  5,455,819      346          1,525,938    off
  3          2,714,323,548  4,117,758,011  0            143          off

The switch also had the following to say when I did a "set ethspeed eth0 auto" on the R710, which I did for the heck of it.

W 12/05/22 14:03:21 00327 FFI: port 2-Excessive undersized/giant packets. See help.
W 12/05/22 14:03:21 00329 FFI: port 2-Excessive CRC/alignment errors. See help.

Here is some more detail from the R710:

ruckus(ap-mode)# get eth

Port  Interface  802.1X  Logical Link  Physical Link      Label
-----------------------------------------------------------------
0     eth0       None    Up            Up 100Mbps full    10/100/1000 PoE
1     eth1       None    Down          Down               10/100/1000

Note: Read Port#N as N+1, if you are referring this CLI output with AP's "Configure :: Ethernet Ports" UI Page.
OK
ruckus(ap-mode)# get power-mode
PoE Configured Mode      : AT
Power Consumption Status : 802.3at Switch/Injector
USB Status               : Disabled
OK

How do I troubleshoot/resolve?

Thank you!

Hi @daniel_m 

I see that the AP is working in AT mode which is fine. Have you checked the power supplying on the Switch side for the APs? I hope power management is not an issue here.
Can you R610 and connect the R610 cable to R710 and see the result? This will eliminate any physical cable\port issues.

You're getting CRC errors, so you have a bad cable or switchport. Try a known good cable, then try another switchport if the replacement cable is no better.

Sorry for the late reply, but thank you for the clue sticks guys!  I traced this down to a bad cable (how does a simple cable that never moves go bad?!), replaced it and we are back to 1000FDx!

Cheers!
